克拉玛依油田五3 东区已进入高含水、高采出程度采油阶段，剩余油呈高度分散状况、地下油水分布规律发生了巨大变化。通过对该区油藏特征研究，开展了动静结合的开发效果分析，加强对剩余油平面及剖面分布规律的认识，概括出剩余油存在类型。针对该区油藏储层物性变化大、非均质性强等特点，提出了可行的挖潜措施，对该区油藏今后的开发调整、提高采收率、保持原油持续稳产具有一定实际意义。

The East 5-3 Block of Karamay Oilfield is now in a stage of high water cut and high recovery percentage; the remaining oil is highly scattered, and the underground oil/gas distribution regularity has changed greatly. Through studying the reservoir characteristics of this block, the analysis of development effect was carried out combining the dynamic and static effects, understanding was enhanced to the remaining oil distribution regularity on plane and profile and the types of remaining oil were outlined. In line with the characteristics of large variation in physical properties of reservoirs and strong heterogeneity in this block, a viable measure for tapping the potential production was presented, which is of somewhat significance for development adjustment, enhance oil recovery and maintaining a continuous plateau production of crude oil in the reservoirs of this Block.
